Unjamming Lightning
summary
Proposal combines local reputation and upfront fees to make channel jamming economically and operationally ineffective, enforcing a fee at the first forwarder and deprioritizing peers with bad behavior. It specifies concrete changes to route selection, pending-payment queue handling, and fee negotiation messages so nodes can refuse or throttle suspected spam. The proposal claims a working prototype and testbed results that cut successful long-lived channel occupancy and restore forwarding capacity for honest users.
